A spider-puss is when the female chooses not to shave her virgina for many months, thus making it a matty clumb of hair. Very simular to a tangled spiders web.

When going down on one's girlfriend, lover or just a one night stand you notice she has been.....well growing her bush for a while"Oh my god love, Is that a tangled web I see before me or are you just growing a spider-puss"
